Antenna Designer Canvas

You can filter the antennas based on Radiation pattern, Polarization,
and Bandwidth.

Using the toolstrip you can also add Cavity backing,
or Reflector backing to the antennas.

You can also specify the Design Frequency of
the antenna. Setting this value scales the antenna to resonate at
the specified frequency. You can also tune the antenna using Antenna
Properties tab during analysis.

When you filter antennas based on Radiation pattern, Polarization,
or Bandwidth, the antenna gallery greys
out the antennas that do not belong to the chosen filter.

Analyze Antenna

You can plot the Impedance and S
Parameter of the antenna based on the specified Frequency
Range in Hz.

You can visualize the Current distribution
on the antenna based on the specified Frequency in
Hz.

You can visualize the 3D Pattern, AZ
Pattern, EL Pattern of the antenna
based on the specified frequency. Here AZ stands
for azimuth and EL stands for elevation.

Use Export to view your antenna
in MATLAB workspace or MATLAB script.

Manually change the antenna properties using the Antenna
Properties tab. In this tab, you can change the geometrical
properties of the antenna, add a dielectric substrate to the antenna,
and change the value and location of the load.

Plot Radiation Pattern of Cavity-Backed Dipole

Use the Antenna Designerapp to plot the radiation pattern of a cavity-backed dipole antenna.

Open the app and click New to show the default dipole antenna.

In the Backing Structure section, click Cavity to create a cavity-backed dipole antenna.

Click Accept.

In SCALAR FREQUENCY ANALYSIS, click 3D Pattern to calculate the radiation pattern of the cavity-backed dipole. The default frequency used is 75 MHz. Click Tile to view both the antenna and the radiation pattern.

Analyze Patch Microstrip Antenna Having Dielectric Substrate

Use the Antenna Designer app to plot the radiation pattern of a patch microstrip antenna with a dielectric substrate.

Open the app and click New. In the ANTENNA GALLERY section, under PATCH FAMILY, click Microstrip Click Accept.

On the Antenna Properties tab, change the groundplane length and groundplane width to 0.120 m. Click Apply to see the changes.

Add an FR4 dielectric as a substrate to the patch microstrip antenna. To add the dielectric, open the Substrate section and set Name to FR4, EpsilonR to 4.8000, and Loss Tangent to 0.0260. Click Apply to see the antenna.

Click 3D Pattern to plot the radiation pattern of the antenna at the default frequency of 1.67 GHz.
